Discoverable mode: General. It means that this device responds only to general inquiries. (Whilst limited mode enabled devices respond to both general and limited inquiries)

Master Switch Supported: true. The application can ask the device to change from master to slave and vice versa within a connection. Why does this matter? Well, once defined a master it could form what's called a piconet (a small network) with up to 7 slaves which share the master's clock. This magic number suits me very well as I'm planing to support up to eight players.

Max Attributes: 10. This has to do with service records. I'll find out more when I study service discovery.

Max Connected Devices : 7. Reference to the piconet.

Max Receive MTU: 512. Maximum Transmission Unit. In some forums talk about setting this size, I need to do some research latter related to the option of living it alone or tweaking it for performance of possible.

Max Service Discovery Transactions : 5. keyword -> Concurrent, which is not bad at all.

Inquiry Scan Supported: false. This device cannot respond to an inquiry request while it has established a link to another device.

Page Scan Supported: false. It cannot accept a connection from a new remote device if it is already connected to another remote device.

Inquiry Supported: false. It cannot start an inquiry while it's connected to another device.

Page Supported: false. It cannot establish a connection to a remote device if it's already connected to another device.

So this device is very limited in the connectivity aspect. I'm adopting the pessimistic approach and I will consider that all devices are like this, in order to aim for a fail-prove communication architecture. This is where the engineering stuff comes into play, in the designing and implementation of subtle workarounds.

This is just an introduction, the real thing comes with inquiries but it's ok for warming up.

I like xmind very much to make brainmaps and conceptual maps but it's only available on its prepackage from in .deb format. I could build it from source, but I wanted to use an utility called alien to transform deb packages into rpm packages and conversely.
